Our inability to change everything should not stop us from changing what we can.

Exactly the point of my quote above - if what's gone is 98% when starting with only 1 person contributing the drug for 10 days on say a 10 acre permaculture garden, I'd be comfortable because I'd expect the healthy soil biome to be able to continue processing it or sequestering it. Fifty years of sewage sludge is a totally different ball game! That said, there's been some excellent bioremediation work on brownfields in England and I was pretty impressed with the results. Usually the issue with such things is one gets a sort of "half-life" situation - the first half of the process seems easy, but the last 2 remaining percent seems to take just as long, and just as many resources to bioremediate as the first 98%. Maybe a better expression is the "law of diminishing returns"?But then there is the question of how much is ok even if 98% is gone.

The adaptive potentials of those who worked in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station under the influence of different treatment methods.
Abstract
A comprehensive evaluation was done in 162 patients-liquidators of the Chernobyl accident. Of these, 80 percent were diagnosed as having stage I and II dyscirculatory encephalopathy (DE), 20 percent were in stage III. It is shown that DE progression is caused by great strain on and breakdown of autoregulatory mechanisms of different biological systems (vascular, central nervous and vegetative, hormonal), and of central regulatory mechanisms as well. Under certain conditions there may occur their breakdown, with syncopal states, crises, and even insults developing in its wake. Treatment and rehabilitation of DE liquidators with pyracetam, vinpocetine, cerebrolysine with magne B6, and phytosorbents (spirulina, quercitrol, and vitapectine) lead to reconditioning of central and autoregulatory compensatory-and-adaptive mechanisms, long-lasting remission, provide complication prophylaxis and promote work activity.

It seems to me that pharmaceutical firms should be able to answer questions about secondary exposure to their drugs and whether or not plants will absorb the drug and expose others to it.

I wonder what percentage of the drugs we take end up in:
1) Urine Filtered by our kidney
2) In Feces, un-absorbed
3) Filtered by our liver sent to our bile/gall-balder/Feces.

However, I don't think either Bokashi or Jenkin's style composting will degrade pharmaceutical products. And Metformin has caused male fish to become effeminate, so ignoring medications is not responsible land-husbandry.

"The Scottish physician Alexander Fleming was the first to suggest that a Penicillium mold must secrete an antibacterial substance" (Wikipedia) That suggests to me that just as how work has been done regarding the balance of different micro-organisms in the soil being desirable for different plants/trees, the same sort of work will need doing to help tweak compost heaps that are being used to digest human waste containing pharmaceuticals. It makes "sense" to me, (but I could easily be wrong) that the presence of a high enough concentration of an antibiotic in excrement would in fact encourage a microbe that was tolerant of +/- used that drug to its own benefit and would discourage a microbe that was bothered by it. This might be exactly what we don't want happening. Just as we try using inputs or specific plants to shift the microbe balance, we may need to try to get similar results through motivated home scientists! Trying to test something as complex as this in a "lab" setting may lead us further astray.It would be nice to figure out which microbes can actually turn these pharmaceuticals and metabolites into CO2. It seems that some microbes actually use the waste material to make more pharmaceuticals.
I have read in the case of brown fields, some work was done to 1. grow "absorbing" plants, 2. compost those plants in a contained space, 3. use this "concentrated toxin" to grow more of the target plants, 4. send the super-contaminated plants to a company that would actually "harvest" the chemical for re-use in industry. Unfortunately, or hopefully, most permies won't be working at that scale, but this might apply to the comment elsewhere about getting hospitals to treat their waste water before it enters the general city waste stream?It seems like similar to heavy metals we can use plants and charcoal to filter out these toxins but where do we now dump these toxic filter?

I am thinking that if a commercial dialysis filter only requires 1% bleach to disinfect, realistically there is less to be concerned with than sad authorities claim.
Argue for your limitations and they are yours forever.
Mike Barkley wrote:My thoughts are that the filter manufacturer uses the term disinfect to indicate that harmful biologicals are made safe with bleach. I think that does not mean that chemicals & medications would be eliminated or possibly even affected. Any of those things trapped by the filter would still be present. Purification & disinfection are two different things.

This is a gigantic book available for purchase at a hefty price or check on-line at www.pdr.net. E-mail for info to: < customer.service@medec.com>. You might also check at the local library or a medical library if you live near one. Many doctor's offices, clinics, and all pharmacies and hospitals have them for use by the staff in various departments. In this reference book you'll find info on pharmacokinetics, metabolism, elimination of drug and route of elimination, half life and other detailed info about drug interactions, uses, warnings, etc. There are also PDR's for other things like Nutritional Supplements, Herbal Medicines and Nonprescription Drugs. You might even ask a medical professional or library if they would give you their old/retired copy when they update to a new edition.
